Curling Hair by Heat.

Hair does not necessarily cusl when merely heated, as a person may go into and remain in an excessively hot temperature without the hair, heated as it will be, curling. The reason generally assigned for its curling when wound on a pair of curling tongs is that the moisture of the side next the iron being evaporated by the heat, the cells in that part approach each other more closely, and this shrinking of one side forms a curve. The curling is partly, however, due to the firmness of the hair, which induces it to retain for a time any form into which it may be forcibly restrained, until its elasticity makes it return after a shorter or a longer period to its original position. This is shown by the old-fash-ioned method of twisting the hair up tightly in curl papers, and keeping it so for a length of time, to induce it to remain more or less curled. Whatever methods are used, they have to be repeated again and again, or else the hair loses its curled appearance, and returns to its natural posißcfc. The persistent use of curling tongs undoubtedly in< jnres the hair by > making it dry and brittle.—[New Yorl| News.
